The thereby is disposed in one position, and cut shell is provided with the usual annular oifby the imperforate portions of the cupbeads 12 to indicate the quantity of material shaped member 15 when in another position, 7 and with a larger annular bead"13 which by this means it will be bvious' that the maconstitutes an inwardly opening annular terial deposited in the shell maybe "sifted 100 channel.

The shaft 24 is threaded for a portion of the distance near one end, preferably the end farthest from the handle 25, as shown disks 27 at their ends. 26 is likewise provided laterally projecting lugs 29 which are adaptbe bent at right angles to the path of the blade, as indicated in Figs. 1 and 2.

he members 26 are curved transversely and likewise curved longitudinally, and terminal disks 27 disposed upon the shaft 24 near its ends. Mounted upon the shaft 24 externally of the disks 27 are washers 30 each having radial lugs 31 adapted to be bent over the superimposed disks between the blades 26, and thus-firmly anchoring the connected blades to the shaft. One of the washers is threaded to engage the threaded portion of the shaft 24 and thus effectually coupling the blades to the shaft. By this means the blades are connected for rotation with the shaft, as will be obvious.

Any required number of blades 26 may be employed, but generally three will be used as shown. he longitudinal curvature of the blades will correspond to th of the cup-shaped members and the cupthis simple means it will be obvious vthatan eflectualsifting of material will be tator blades according to the position of the outer or oscillating cup-shaped member, as before described. By curving the blades 26 transversely, they pickup a portion of the material and carry it down. upon the remaining material and thus materially; increase the efi'iciency of the siftrepresented at 34 to the shell, as sh aving thus described the invention, what is claimed as new is zwill preferably be attached own.
